TELESYSTEM CALIBRATION FACILITY Russian patent published in 2017 - IPC G12B13/00 

FIELD: oil and gas industry.

SUBSTANCE: invention is intended for metrological certification of telemetry system sensors to detect errors of inclination when drilling in three-dimensional space in the projections to axes X, Y, Z. Telesystem calibration facility is made of nonmagnetic material using reliable orientation devices of high accuracy relative to magnetic force of the Earth and to rotation plane of swing platform 1. Device for telesystem fixation and centering in swing pipe 10 is formed of two cylinders 18, 19, inserted one inside the other, concentrically exposed by wedge sleeves 20, 21. Telesystem is installed in the inner cylinder 18 of the swing pipe, wherein the accuracy of its installation in the swing pipe 18 is achieved by using interchangeable gripping collets 24 and ring wedges 25 installed oppositely from each end of the pipe.

EFFECT: improved accuracy of telesystem calibration, which ensures minimal drilling trajectory deviation from the calculated one; standardization of facility use for a number of telesystems of cylindrical shape.
